EGR removal

I decided to remove the EGR unit for two reasons: First, it is supposed to drain power and second, it is said to distribute grease into the turbo.
I can definitely confirm the grease, as you can see from the pictures below. There was lots of gunk in the system from where the EGR pipe joins the intercooler pipes.
After the removal I also think I can sense some more power and a more subtle throttle response. Yet, this is purely subjective.
You can buy the necessary blanking plate and the replacement gasket for a few euros directly from Land Rover. I went for a complete set of silicone hoses and and blanking plate, which I found a good offer for at Trailgard.

EGR removal:
The EGR valve as fitted to the 300Tdi engine.
The unit is removed using a 6mm allen key. It is advisable to soak the two bolts in WD40 for a night to prevent them from snapping.
There was lots of grease in the pipeworks onward from where the EGR pipe joins the intercooler plumbing.
More grease.
Here you can see the old EGR inlet.
The two bolts, the blanking plate and a new gasket to replace the worn and rusty one.
Everything fitted and tigthened to 25nm with a torque wrench.
You can spot a piece of the blue silicone hose that I used as a replacement for the original ones.
Silicone is supposed to be much more durable and doesn't flex as much as the original material, which is said to cause a drain on turbo power.
You need some sort of replacement because of the missing EGR inlet. So, the money for the blanking plate, gasket and silicone hoses was only a little more than LR replacement stuff.
After everything was fitted and double checked, I took a test drive. I think I noticed a slight increase in power and a more direct turbo response. I can now accelerate smoothly from 80 to 130 kph without any noticeable lag. Acceleration from low speeds seems also more direct and a bit more fierce.
